Just the tip of the iceberg, as we suspected.
In regards to this guy - I prefer the phrase "tip of the dunghill"
There are people in the negatives. I can't tell you what they're all doing but in the 3rd from left, a person is on their knees while wearing white pants and a dark colored shirt.
Keep in mind that negatives are, well,
negative. So it is likely that the probable kneeling person is wearing dark pants. Which, IMO, additionally also rules out that said person is naked - AFAIK, no victims were black, at least not to the degree that they would photograph quite as darkly. So the photo
might even not be connected - while the pose can seem sinister, we cannot even be sure about what we're seeing, let alone the context. For example, this is how I play with my cat.
In regards to the artwork - it might not be connected. This style does not strike me as unusual, per say. Can be a reflection of the artists own struggles with identity, self esteem, mental health, growing up pains, being a woman in this damn society etc. AFAIK, none of the paintings displayed violence against women per say.
A sad little illustration to that: a friend of mine had her school-age daughter die in a freak accident (not suicide). She loved to do art and the last artwork she did was of an abstract human being one with the stars and universe. Stuff happens. Her kid was being existencial like all young teens. RHs daughter might have had her own troubles and worries - with a dad figure like that, I find it rather likely. More likely to happen than what happened in my friends case, anyways.
